What is a redesign traffic-drop audit?
A redesign traffic-drop audit compares pre-launch and post-launch evidence to identify whether organic loss came from redirects, canonicals, sitemap discovery, robots, noindex, internal links, content, speed, tracking, or demand changes.
When it breaks
It breaks when teams only look at GA4 sessions, only inspect one URL, or make more site changes before separating measurement loss from search visibility loss.
Inspect first
Inspect GSC clicks, impressions, pages, queries, URL Inspection samples, GA4 organic landing pages, tag changes, old URLs, new sitemaps, and priority redirects first.
